 Package updates advance the package-source revision and all five declared digests atomically. The immutable-source validator reads each package blob from that Git revision, recomputes its digest and canonical slug, and rejects a descriptor that does not match those historical bytes.

They intentionally have no required write-tool gate: deterministic report/diff postconditions reject no-op writes while allowing honest no-change maintenance.
+All five packages support direct import through `wp_agent_import_runtime_bundles()` and retain the source-grounded workspace-only editing boundary. Technical bootstrap has an Agents API completion gate that requires a workspace documentation write before it can finish, so a fresh surface cannot complete as prose only. Maintenance and the other no-change-capable lanes intentionally have no required write-tool gate; deterministic report/diff postconditions continue to reject no-op writes while allowing honest no-change maintenance.
